Taschenbuch. Zustand: Neu. Neuware -Description:Sperm DNA integrity is crucial for fertilization and development of healthy offspring. The spermatozoon undergoes extensive molecular remodeling of its nucleus during later phases of spermatogenesis, which imparts compaction and protects the genetic content. Testicular (defective maturation and abortive apoptosis) and post-testicular (oxidative stress) mechanisms are implicated in the etiology of sperm DNA fragmentation (SDF), which affects both natural and assisted reproduction. Several clinical and environmental factors are known to negatively impact sperm DNA integrity. An increasing number of reports emphasizes the direct relationship between sperm DNA damage and male infertility. Currently, several assays are available to assess sperm DNA damage, however, routine assessment of SDF in clinical practice is not recommended by professional organizations. This article provides an overview of SDF types, origin and comparative analysis of various SDF assays while primarily focusing on the clinical indications of SDF testing. Importantly, we report four clinical cases where SDF testing had played a significant role in improving fertility outcome.Books on Demand GmbH, Überseering 33, 22297 Hamburg 224 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The ESHRE Special Interest Group in Embryology published the Atlas of Embryology in 2000 as a supplement to Human Reproduction. This initiative was received with acclaim and has become a very valuable reference that is used by embryologists all over the world.We have undertaken to produce a new edition that completely updates the first edition and have chosen to publish it as an online document that provides the additional advantages of flexibility for revision and ease of consultation. The ease of online publication means that the Atlas can be updated on a regular basis and we intend, in the first update, to add chapters on cryopreservation and time-lapse monitoring. The new edition includes almost 400 figures grouped in four chapters: the oocyte, the zygote, the cleavage stage embryo and the blastocyst. Each chapter has a brief introduction and is then divided into several subheadings which are described by a short text and by a series of images whose features are detailed in a legend and, when needed, by specific diagrams.Books on Demand GmbH, Überseering 33, 22297 Hamburg 288 pp. Englisch.
